FN America Awarded $119M U.S. Army Contract for M4/M4A1 Carbine

FN America LLC was awarded a firm-fixed-price contract, worth around $119 million, by the U.S. Army Contracting Command (ACC) for M4/M4A1 carbine.

Bids were solicited via the internet for the contract (W15QKN-20-D-0006) with six received. Work locations and funding will be determined with each order, with an estimated completion date of Jan. 30, 2025.

The M4 carbine is a 5.56×45mm NATO, air-cooled, gas-operated, magazine-fed carbine which is a shorter and lighter variant of the M16A2 assault rifle. The carbine has a 14.5 in (370 mm) barrel and is equipped with a collapsible stock, an adaptor rail system and a backup iron sight.

The carbine is extensively used by the U.S. Armed Forces and is largely replacing the M16 rifle in the Army and Marine Corps combat units as the primary infantry weapon and service rifle. The base M4 variant has semi-automatic and three-round burst firing modes (like the M16A2 and M16A4), while the upgraded M4A1 variant has semi-automatic and fully automatic firing modes (like the M16A1 and M16A3).

The M4 Product Improvement Program (PIP) converts fielded M4s to M4A1s by adding a heavy barrel, a fully automatic capable trigger mechanism and an ambidextrous fire control assembly. Weapons are modified via U.S. Army Tank-Automotive and Armaments Command (TACOM) and Anniston Army Depot (ANAD) mission teams using Modification Work Order instructions beginning with pre-built kits assembled at ANAD in Alabama.

The M4A1 can be mounted with the M203A2 Grenade Launcher, M320A1 Grenade Launcher or the M26 Modular Accessory Shotgun System.
